Wheelset – Fulcrum

Fulcrum Wheelset Technologies

2:1 Two-to-One™
When you push on the pedals, the rotational force on the sprocket induces a slackening of the freewheel spokes with a consequent loss of rim tension. This results in undesirable flex of the whole wheel and an unavoidable loss of energy. Fulcrum® has solved this classic cycling problem with its 2:1 Two-to-One™ Spoke Ratio patent, by doubling the spokes in the critical zones.

As a result there are two spokes which carry out the function of one, slackening and torsion are limited and the transfer of the athlete’s power is much more effective Also, thanks to this system, spoke tensions are balanced more evenly between drive and non-drive sides and the fatigue life of the rim, hub and spokes is lengthened.

Ceramic Ultimate Level Technology, CULT™
CULT™: it stands for Ceramic Ultimate Level Technology. But, above all, it is the technology we have developed, fine-tuned, and then adopted exclusively for the realization of the bearings with ceramic balls.

Behind CULT™ is the exclusiveness of Cronitect® steel, using the “Advanced by FAG” technology by Schaeffler Group., for the bearing races. This is an incredibly robust and corrosion-resistant stainless steel, with a surface thermo chemical treatment that makes it extremely resistant to corrosion.

The final result? Amazing: wheels with CULT™ ball bearings are 9 times smoother than wheels with traditional bearings. A benefit that translates into a great advantage when it comes to saving energy and seconds or even minutes.

Thanks to a special impression in the valve area, the tubes are fitted with the maximum precision while keeping the tube perfectly stable inside the tyre. Housing the valve for tubeless tyres is also risk-free, with the unquestionable advantage that there are never any air infiltrations caused by non-ideal positioning when fitting.

Advantages: Tests have highlighted an unique increase in smoothness. Because there is no tube, the friction caused by rubbing against the tyre is eliminated, while the perfect adherence of the tyre to the rim prevents the dispersion of energy.

Tubeless tyres do not suffer from sudden deflation when punctured which is a great advantage in safety terms. There is also no risk of snake bites as there is no tube to rupture.
What if a tubeless tyre gets punctured? There’s nothing to fear…With Fulcrum® 2-Way Fit™ you can remove the tubeless valve and fit in a standard clincher tire that will let you ride back home.

Dynamic Balance™
The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side.
For top models, this is obtained by a special operation on the section of the rim opposite the rim joint.
For entry-level models, Dynamic Balance™ is obtained by using two oversized spokes in the section opposite the joint. The result is a wheel with perfectly balanced rotational dynamics.

Maximum Compatibility
With the new Fulcrum® freehub body dedicated to non-Campagnolo® drivetrains you will be able to exploit the maximum versatility of your current system. We have developed a freehub body that is perfectly compatible with Shimano Inc. 8, 9 and 10 speed systems and Sram Co. 10 speed ones.

Spoke Anti-rotation System
This new system raises the concept of spoking to new heights of performance. The Fulcrum® engineers have redesigned the spokes and the hub housings to create a solid and unmoveable whole.
The result is that the spokes

a) will never lose their initial tension, thus keeping the wheel perfectly reactive and centred.

b) will remain in the position that was found in wind tunnel tests to ensure the best aerodynamic penetration possible.

The spoke antirotation system comes in all: Racing Speed and Racing 3 2WF

MoMag™
Though they have no holes in the rim bed, Racing3, Racing1 and RacingZero rims have spokes tensioned by traditional nipples. This makes tensioning and changing the spokes extraordinarily easy, and does away with questionable anchoring systems on the rim. This solution was made possible thanks to the Fulcrum® MoMag? patent which exploits magnetic power and a good dose of ingenuity to guide the nipples to the correct rim holes.

Fulcrum Racing Speed XLR Carbon Tubular Wheelset
Racing Speed™ wheels are much loved by professional cyclists. Their widespread diffusion is due to the wheel’s many features: the high rim profile combined with lightness make this model particularly suitable for the most varied racing situations. The Racing Speed XLR version of the wheel has been completely renewed. The body is made of carbon. The balls of the bearings implement CULT technology with its super-high strength and smoothness thanks to Cronitect stainless steel with thermo-chemically treated surface layer. The rim has a 50 millimetre profile and is supported by 18 radially-laced spokes in the front wheel and 21 in the rear with doubling on the freehub side using Two-to-One technology.

Fulcrum Racing Speed Carbon Tubular Wheelset
With the addition of the Racing Speed™ model to the range, Fulcrum has democratised the high profile carbon fibre wheel. Racing Speed™ reflects every feature of the design lines of the Racing Speed™ XLR model, becoming the entry level model of the high profile carbon range. The rim is entirely made of carbon fibre, with a height 50 mm, and is made using a particular technique by which the carbon fabric is aligned so that the resulting rim is always balanced.

Fulcrum Racing Zero 2-way Fit
The Fulcrum Racing Zero 2-way Fit (Black/Red) Wheels 2010 are a superb wheelset. Red spokes, black rims: wheels that are absolutely unmistakeable in the middle of the peleton. Two powerful colours and exclusive technology stand out from the crowd and make these wheels unique in terms of performance and personality. Racing Zero wheels are at the top of the Fulcrum® range.

The 2-Way Fit™ (Tubeless & Clincher) version is fitted without tubes, mostly to the advantage of safety and comfort but also in terms of performance. This is an advantageous product which offers a double choice, allowing you to choose the benefits of tubeless or the practicality of clincher tyres. Thanks to Ultra-Fit ™Tubeless technology, the use of the tubeless tyres drastically improves smoothness and reduces the risk of snake biting on rough roads. The release of air is also gradual in the event of puncturing: there is no risk of sudden deflation.

Fulcrum Racing 1 2-way Fit
These are top of the range wheels which as also suitable for everyday use. Even if Racing 1 2-Way Fit™ wheels have been conceived for racing, it is also ideal for everyday training. The new version of the Racing 1 2-Way Fit™ has been slimmed down by a full 50 grams, thanks to the introduction of new spokes in aluminium with aerodynamic profile and aluminium nipples. Ultra-Fit™ Tubeless technology ensures perfect tightness between the tyre and rim and the inflation pressure remains constant over time. Thanks to 2-Way Fit™ it is also possible to fit traditional clincher tyres with tubes. The application of tubeless technology guarantees excellent smoothness.

Fulcrum Racing 3 2-Way Fit
The Fulcrum Racing 3 2-Way Fit wheels differ from the Racing 3 version also in other aspects. First of all, the weight, as this version is a full 80 grams lighter, a huge difference for this type of wheel. In fact, Fulcrum has used differentiated rims, 24mm for the front and 30mm the rear, so that the front wheel, along with radial spoking, produces perfect aerodynamic penetration. The rear wheel, on the other hand, was developed to instantaneously transmit the cyclist’s power, the reason why Fulcrum chose a more rigid 30mm rim together with the now celebrated Two-to-One spoke ratio. Here, too, Fulcrum Dynamic Balance keeps the Racing 3 2-Way Fit wheel perfectly stable even at high speeds.

Fulcrum Racing Zero Clincher
Racing Zero is the top wheel of the Fulcrum® aluminium range. Its extraordinary performance features and high impact aesthetics make it stand out from the crowd. The front and rear wheel profiles are differentiated: the 26 mm height for the front guarantees excellent aerodynamic penetration, while the 30 mm of the rear wheel means extremely effective transmission of your pedalling power. Both rims feature the special Fulcrum lightening between the anchoring points of the spokes and the patented Dynamic BalanceTM system that guarantees the maximum stability of your bike even at high speeds.

Fulcrum Racing 1 Clincher
Racing 1 wheels have competition in their DNA. If you’re looking for a lightweight wheel that gives the best performance under any condition and has a marvellously aggressive look, you’ve found it. The aluminium rims have a differentiated profile front and rear. The front wheel height is 26 mm to achieve perfect aerodynamic penetration, while the rear increases to 30 mm to provide all the stiffness necessary to transmit every watt of your power. Both rims feature the characteristic Fulcrum® toroidal milling between the anchoring points of the spokes, and the fact that the rim grooves do not have holes translates into greater torsional stiffness and greater vertical elasticity.

Hi, it’s actually more advisable to use parts that are meant for fixie bike.
Those components that you mention are build for road racing. You can check out our fixed gear components @ http://sgbmx.wordpress.com/fixed-gear-components/. I am sure you can find what you need there 🙂

Yes, the price for Fulcrum racing speed is around $3300. If you are keen, you can come over our shop to discuss further. We can still adjust the pricing slightly if you are paying in cash. Alternatively, you can also consider Stella Azzurra Calibro 50F – 50R (* Made in Italy) @ $2100 only.

Nicksaid

Fulcrum Racing Zero is about $1500. It will still have the click like Fulcrum 5 & 7 unless you insert more oil, or bring back for servicing as it starts to get season. But it’s definitely a better wheelset option due to the ceramic bearings.
